Abstract
Process for the manufacture of ammonium, alkali metal or alkaline earth metal orthophosphates, comprising a first stage in which the commercial phosphoric acid is reacted with a water-insoluble amine to produce a single organic phase containing the newly formed amine phosphate and wherein the resulting organic phase is contacted in countercurrent with the ammonium, alkali metal, or alkaline earth metal chlorides to obtain the corresponding primary orthophosphate of ammonium, alkali metals or alkaline earth metals in solid phase by direct precipitation in organic phase; a second step in which the amine chloride contained in the organic phase from the previous step is reacted with a strong alkali or an aqueous solution of said alkali to recover the amine in its free form and recirculate it to the first stage; a third stage in which the solid phosphate produced in the first stage is washed, to recover the entrained organic phase, with a suitable solvent, which is then recovered by distillation, dried, cooled and sieved.
